JOHANN GEORG WEISSMANN, OF SOHWEINAU, GERMANY.

HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 512,778, dated January16, 1894.

Application filed September 20, 1893. Serial No. 486.023. (No model.)

To all whom it may concern:

Be it known that I, JOHANN GEORG WEISS- MANN, farrier, of Schweinau,near Nuremberg, in the Kingdom of Bavaria and Empire of Germany, haveinvented certain new and useful Improvements in Horseshoes withExchangeable Toes, of which the following'is a specification.

My invention consists in a horse-shoe provided on its underside at thefront part with two rabbets inclined toward each other, a detachabletoe-calk having the top-plate fitting between said rabbets and providedwith a rubber-plate, said toe-calk being held in place by fasteningdevices passed through apertures of the top-plate of the toe-calk at therear edge of the front part of the shoe.

The invention also consists in the construction and combination of partsand details, which will be fully described hereinafter and finallypointed out in the claim.

In the accompanying drawings, Figure 1 is a face-view of the under sideof myimproved horse-shoe, with a calk held in the same.

Fig. 2 is a side view of the shoe without the calk. Figs. 3 and4areside-views of different kinds of calks, and Fig. 5 is a front-view ofthe shoe, with the calk inserted.

Similar letters of reference indicate corresponding parts.

The horse-shoe A is provided at the middle of its'front with tworabbeted or under-cut flanges a on the under side, which flanges areinclined toward each other and serve to receive the top-plate of adove-tailed toe-calk b.

In order to prevent the toe-calk. from becoming detached, its top-plateis of such length that it extends beyond the rear edge of the front partof the shoe, and the said topplate' is provided at its inner or rear endwith an aperture for receiving a bolt 6. In case the toe-calk becomesloosened, a screw can be screwed through an aperture f in the rearextension of the top-plate of said toe-calk, which apertureis slightlyin advance of the aperture through which the bolt e is passed.

For the purpose of more firmly securing the toe-calk and preventingrattling of the same on the shoe, a cushion-plate d of rubber is appliedon the upper surface of the top-plate of the calk, so as to be betweenthe bottom of the shoe and the upper surface of the topplate when thecalk is fastened on the shoe.

In winter the sharp calk shown in Fig. 4is used, and this can readily bemade by any farrier out of the Worn out summer calks, of which one isshown in Fig. 3, the summer calks having a greater width at the base.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination, with a horseshoe having two undercutflanges on its under side at the front, which flanges are inclinedtoward each other, of a dovetailed toe-calk having a topplate fittingbetween the undercut flanges, a rubber cushion-plate on said top-plate,and fastening devices passed through apertures in the top-plate of thetoe-calk after the same has been inserted and beyond the rear edge ofthe front part of the shoe, substantially as set forth.

In testimony that I claim the foregoing as myinvention I have signed myname in presence of two subscribing witnesses.-
